London-based pop act Rita Ora followed her No. 1 single of two weeks ago, "How We Do (Party)" (Roc Nation/Columbia/Sony Music Entertainment), with a chart-topping debut for her debut album Ora yesterday (Sunday). Emeli Sandé's Our Version of Events (Virgin/EMI) fell to No. 2, but overtook Adele's 21 (XL Recordings) during the sales week as the U.K.'s bestselling album of 2012 so far. Meanwhile, girl group Little Mix made it two No. 1 singles from two releases with "Wings" (Syco Music/Sony Music Entertainment).

Ora's album hit the top as "How We Do" dipped 2-3 and her previous No. 1 with Tinie Tempah, "R.I.P.," rebounded 47-23. "Hot Right Now," the DJ Fresh chart-topper on which she guested, reappeared in the top 75 at No. 51 and "Young Single & Sexy" charted at No. 54. Sandé's set has now climbed to total sales of 667,000, moving 9,000 units ahead of 21, which slipped 15-16 on the new chart.

It was also a banner week for Icelandic six-piece Of Monsters & Men, whose Universal Republic album My Head Is An Animal, released nearly a year ago in their home territory and in the spring in Europe and North America, debuted in the U.K. at No. 3. Its appearance has been prompted by the continuing rise of the single "Little Talks," which has progressed 35-21-12.

British alternative rock survivors Elbow debuted at No. 4 with Dead in the Boot (Fiction/Polydor/Universal), a new collection of b-sides and rarities. Plan B's Ill Manors soundtrack (679/Atlantic/Warner Music) climbed back 16-7 and fun.'s Some Nights (Fueled By Ramen/Atlantic/Warner Music) raced 35-8, as the title track rose 24-14 on the singles survey. Alanis Morissette, after a raft of U.K. media coverage, saw her new Columbia/Sony Music Entertainment album Havoc and Bright Lights open at No. 12. Now! That's What I Call Music 82 (EMI TV/Universal Music TV) is No. 1 on the compilation chart for a sixth straight week.

Female pop quartet Little Mix followed their victory in the 2011 series of "X Factor" with a No. 1 version of Damien Rice's "Cannonball" just before Christmas. The follow-up "Wings" sold 107,000 units last week, according to the Official Charts Company. Last week's No. 1 single, Sam & the Womp's "Bom Bom" (One More Tune/Stiff/Warner Music), slipped into the runner-up spot.

Public Enemy's "Harder Than You Think" (Slam Jamz), featured in Channel 4's Paralympic Games coverage, climbed again 11-4, with "Good Time" (Interscope/Universal Republic) by Owl City and Carly Rae Jepsen up 17-5. Lucy Spraggan, a contestant on the new "X Factor" series, charted at No. 11 with her self-released "Last Night (Beer Fear)," despite the track and her album Top Room At The Zoo being pulled by digital retailers last week "in preparation for some things coming up," as Spraggan put it on her Facebook page.
